Natriuretic 中文 Natriuretic peptides (NPs) are a fascinating family of peptide hormones that play a crucial role in regulating the body's fluid balance, blood pressure, and cardiovascular function. Primarily produced by the heart, these peptides are released in response to increased cardiac stretch or pressure. Understanding their function and measurement is vital for diagnosing and managing various cardiovascular conditions.人N 端B 型利鈉肽(NT-proBNP) 是一種帶有His 標籤的重組蛋白。 NT-proBNP 也稱為BNPT。

The Natriuretic Peptide Family: ANP and BNP

The natriuretic peptide family includes several key members, with the most clinically relevant being atrial natriuretic peptide (ANP) and brain natriuretic peptide (BNP).

* Atrial Natriuretic Peptide (ANP), also known as atrial natriuretic peptide in Chinese or 心房利钠肽 (xīnfáng lìnàtài), is synthesized and released by the atrial myocytes (heart muscle cells) of the heart12193B00 | 檢驗項目| 為民服務 - 國立臺灣大學醫學院附設醫院雲林分院. Its release is triggered by atrial distension, often due to increased blood volume or pressure. ANP functions to promote the excretion of sodium and water by the kidneys, leading to vasodilation (widening of blood vessels) and a reduction in blood pressure脑利钠肽（BNP）和N末端脑利钠肽（NT-proBNP）. It also inhibits the renin-angiotensin-aldosterone system, further contributing to blood pressure regulation.

* Brain Natriuretic Peptide (BNP), or brain natriuretic peptide in Chinese (脑利钠肽, nǎo lìnàtài), is primarily produced by the ventricular myocytes心房利鈉肽（英語：atrial natriuretic peptide），又稱心鈉素、利鈉素、利尿素、血管舒張素。屬於利鈉肽(Natriuretic peptides)家族之一員，其另包含腦利鈉肽(brain .... While initially discovered in the brain, its main source in the body is the heart ventricles. BNP is released when the ventricular walls are stretched or subjected to increased pressure, a common occurrence in conditions like heart failure. BNP shares many of the physiological effects of ANP, including promoting natriuresis (sodium excretion), diuresis (water excretion), and vasodilation. It also helps to counteract the effects of vasoconstrictors like angiotensin II, thereby reducing the workload on the heart. BNP is a critical biomarker for diagnosing and assessing the severity of heart failure.

Another important related peptide is N-terminal pro-brain natriuretic peptide (NT-proBNP). This is a precursor molecule to BNP and is also elevated in individuals with heart failure. NT-proBNP has a longer half-life than BNP, making it a useful marker for monitoring chronic heart conditions. The measurement of both BNP and NT-proBNP is crucial for the clinical evaluation of patients with suspected or confirmed heart conditions.

The Role of Natriuretic Peptides in Heart Failure

One of the most significant applications of natriuretic peptides is in the diagnosis and management of heart failure. When the heart is unable to pump blood effectively, it leads to a buildup of fluid and increased pressure within the heart chambers.B型利钠肽是心肌细胞分泌的一种神经激素利钠肽（亦称心钠肽），其主要功能是增加尿钠排泄，降低血管紧张素-醛固酮引起的血管收缩及血压升高。心室肌细胞为BNP主要储存和 ...

The BNP test is a common laboratory test used to assess cardiac function.

* BNP levels can also be used to predict prognosis and monitor the effectiveness of treatment for heart failure. For patients with heart failure, BNP levels are typically higher than in healthy individuals.

* Research has explored the use of BNP and NT-proBNP in pediatric cardiovascular diseases as well. Studies indicate that BNP levels can correlate with a child's age and sex, and are important indicators for assessing cardiac function.

Beyond Heart Failure: Other Applications

While heart failure is a primary focus, natriuretic peptide measurement has broader applications in cardiovascular medicine. They can help identify individuals at risk of cardiovascular events and guide treatment strategies. The natriuretic peptide receptor B (NPR2) is also being studied for its potential role in bone development and other physiological processes.NT-proBNP ；原生B型利鈉利尿胜
